turns out the diagnostic port on the benz wasn't lying, about my injector codes, knock sensor codes, and the smog pump code..

and i know the knock sensors 1 just 1 thing now..

and the injectors shorting might be from a bad ground.. will clean it up with isopropyl alcohol and a toothbrush, as well as injector cleaner.. and maybe even a light wetsanding.

i hope the wires arn't bad.. as i only bought 16 gauge wire.. cause if they are i need to spend more money on 12/14 gauge wires as well.. or maybe i can get a little bit cut as i don't need that much..

its sad my idle wasn't even that bad with wires just nutted..

so my idle dropping was probably my vacuum leaks honestly, as i have many vacuum leaks.
